Upon arrival set thermostat to cool mode, went to furnace and checked blower, blower was vibrating. Tightened up bolts in back and check the pin in front on the blower. After tighten the vibration went down. Checked static pressure, check blower amps, and were good. Went to outdoor unit and checked refrigerant levels were good, check all electrical components and were good. At this time system are running properly. After discussing mini spilt issue with customer they elected not to assess unit today.
